In simulation environments, prediction of path losses, maximum communication coverage for each node and received signal strength are calculated by using propagation model. However, most of the simulation tools only offer simple propagation model that neglected obstacles in the propagation environment. This paper reviews a variety of more realistic propagation models for Wireless Sensor Networks and...
We develop several hardware and software simulation blocks for the TinyOS-2 (TOSSIM-T2) simulator. The choice of simulated hardware platform is the popular MICA2 mote. While the hardware simulation elements comprise of radio and external flash memory, the software blocks include an environment noise model, packet delivery model and an energy estimator block for the complete system. The hardware radio...
